Hi,
As i can see now, the packets start to go through the right interface with the right address but no reply still. The tunnels after a long time it getting established. If i make service ipsec restart ... the first think what iv got from the ipsec auto --up tunnel name or ipsec auto --status is this:
Quote:
000 #7: "tunnelname":500 STATE_MAIN_I1 (sent MI1, expecting MR1); EVENT_RETRANSMIT in 2s; nodpd; idle; import:admin initiate
000 #7: pending Phase 2 for "tunnelname" replacing #0
After some time the tunnels status is:
Quote:
000 #22: "tunnelname":500 STATE_QUICK_I2 (sent QI2, IPsec SA established); EVENT_SA_REPLACE_IF_USED in 27637s; newest IPSEC; eroute owner; isakmp#7; idle; import:admin initiate
000 #22: "tunnelname" esp.b18cc17@<pub_ip_other_site> esp.c59dvg@<pub_ip_my_site> tun.0@<pub_ip_other_site> tun.0@<pub_ip_my_site> ref=0 refhim=4294901761
000 #7: "tunnelname":500 STATE_MAIN_I4 (ISAKMP SA established); EVENT_SA_REPLACE_IF_USED in 27870s; newest ISAKMP; lastdpd=-1s(seq in:0 out:0); idle; import:admin initiate

Here is the list of the iptables:
Quote:
iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MYNAT all -- 172.28.2.0/24 anywhere
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain MYNAT (4 references)

Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
Chain OUTPUT (policy ACCEPT)

And this is the ping and tracepath results:

Hi Guys,
Please could you tell me if it is possible to have a single rule/filter to allow a certain port range instead of a separate rule for each port?
I'm sure it must be possible but I am unable to find the syntax.
Thanks
